The theremin The controlling section generally consists of two metal antennas to sense the relative position of the player’s hands. These sensors control audio oscillator(s) for frequency from one hand, and volume from the other. The electric signals from the theremin are amplified and sent to a loudspeaker. To play the theremin, the player moves his hands around the two metal antennas, which control the instrument’s frequency (pitch) and amplitude (volume). The theremin is widely associated with “alien”, surreal, and eerie-sounding portamento, glissando, tremolo, and vibrato sounds, due to its use in film soundtracks such as Spellbound and The Lost Weekend.
